GM Service Manual Online
For 1990-2009 cars only

This section includes basic information about the map database.

The maps are stored on a DVD-ROM. The 48 contiguous United States, Hawaii, and Canada are contained on one disc. The map database includes interstate freeways, state highways, country roads, and major and general streets.

Refer to the "Navigation System Map Disc" manual to view the explanation of map coverage. The map disc manual will be in the map DVD case when the vehicle is delivered from the factory.

Installing the Map DVD

Your dealer may have installed the map DVD. If the map DVD was not installed, do the following:

  1. Turn the ignition on.
  2. Load the map DVD into the DVD slot by inserting it partway. The system will pull it in.

Once the map DVD is inserted correctly, you will have the following two language choices:

    • ENG (English)
    • FR (French)

Select the language at this time. See "Language" under Configure Menu for more information. Once a language has been selected, touch the NEXT screen button to plan a route. The map will appear showing your vehicle's current position.

Map Adjustments and Scales

The system allows you to adjust the scale of view on the map. The map will scroll automatically based on the direction the vehicle is traveling.

To view a larger or smaller scale of the map, touch zoom in or zoom out. The scale of a map can range from 1/32 of a mile (0.05 km) to 128 miles (206 km). See "Hard Keys" under Using the Navigation System for more information.
